Trans Mountain is proposing an expansion of its current 1,150-kilometre pipeline between Strathcona County (near Edmonton), Alberta and Burnaby, BC. The proposed expansion, if approved, would create a twinned pipeline that would increase the nominal capacity of the system from 300,000 barrels per day, to 890,000 barrels per day.
Some quick facts include:
- Projected capital cost: approximately $5.4 billion
- Approximately 980 km of new pipeline
- Reactivation of 193 km of reactivated pipeline
- 12 new pump stations to be built
- 20 new tanks to be added to existing storage terminals in Burnaby (14), Sumas (1), and Edmonton (5)
- Westridge Marine Terminal in Burnaby to be expanded with 3 new berths
- Existing line to carry refined products, synthetic crude oils, light crude oils with capability for heavy crude oils
- Proposed new line to carry heavier oils with capability for transporting light crude oils
This is not the first time the Trans Mountain line has been expanded. In fact, since operation began in 1953, the capacity of the pipeline system has been increased numerous times, with the initial expansion in 1957. The most recent expansion project took place between 2006 and 2008 with the construction of 13 new pump stations and modifications to existing stations. Also during this time, the Anchor Loop project added 160 kilometres of new pipe through Jasper National Park and Mount Robson Provincial Park between Hinton, Alberta and Hargreaves, BC.
At present, the Westridge Marine Terminal handles approximately five tankers per month. Should the proposed expansion be approved, the number of tankers loaded at the Westridge Marine Terminal could increase to approximately 34 per month.
